ES-SCLC, Tarlatamab, AMG 757, AB248, Imdelltra
Brief summary
The primary objective for dose exploration and dose expansion is to evaluate the safety and tolerability of tarlatamab in combination with AB248. The primary objective for dose exploration only is to determine the recommended dose for expansion and/or maximum tolerated combination dose (MTCD) of AB248 in combination with tarlatamab.
Interventions
Administered as an IV infusion.
Administered either as an IV infusion followed by a flush or using a syringe pump without a flush.

Eligibility
Inclusion criteria
1. Participant has provided informed consent before initiation of any study-specific activities/procedures. 2. Participants ≥ 18 years (or ≥ legal age within the country if it is older than 18 years) at the time of signing the informed consent. 3. Participants with histologically or cytologically confirmed ES-SCLC that has progressed or recurred following at least 1 line of anti-cancer therapy for ES-SCLC. 4. Participants must have at least 1 measurable lesion as defined by RECIST 1.1 within 21-day screening period, not previously irradiated. 5. Participants must have adequate organ function (hematological, coagulation, cardiac, pulmonary, kidney, and liver). 6. Participants must submit a fresh tumor biopsy at screening unless a new biopsy cannot be performed safely or is infeasible. Participants who cannot provide fresh tissue may provide archival tissue that was collected after last anticancer therapy.
Exclusion criteria
1. Symptomatic central nervous system (CNS) metastases. 2. Participants with brain metastases may be eligible if criteria defined in the protocol are met. 3. Prior therapy with any delta-like ligand 3 (DLL3)-directed therapy (including tarlatamab). 4. Prior interleukin (IL)-2, IL-7 or IL-15 targeted therapy. 5. Baseline (at rest) requirement of supplemental oxygen.
